Ok so I was wondering guys.
A lot of you have the new 4.2 and on the samsung site it says
"Use your player as a Bluetooth® device. Your player complements your current phone. Pair your current phone to the Galaxy Player 4.2 and start using your Galaxy Player 4.2 to as a communication tool. Now you can answer calls from your Galaxy Player via Bluetooth."

And I have the Galaxy 4.0 and super happy with it, but I would like to have that function to use it as a extended communication tool. So who can tell me what program it is and where I can get the .apk

It's not only an app that controls these functions, you have to have a device that supports the proper bluetooth profiles for it to work and the 4.0 and 5.0 unfortunately (and a FAIL on samsungs part) don't support those profiles.

Still, so what? You have a separate phone, it rings in your left pocket, you pick up the Galaxy from your right pocket, it hooks up to the phone via bluetooth and you take the call on the Galaxy. If you have the phone in your pocket (and you have to- because bluetooth is very limited in range)...why not just answer the call on the actual phone? Just to look cool with a big new device rather than taking the call on your old Nokia clamshell?

I think a usage scenario might go more like this... you are listening, with earbuds, to music on your SGP when when a call comes in. You can either pause the music, take the earbuds out, find the phone (Bluetooth range is limited but not needs to be in my other pocket limited) and answer the call or you can pick it up from the device you are already using, without ever having search for the phone or take the earbuds out (on account of the built-in mic & clicker.)
